Nice! I just finished building my lower receiver and just ordered a complete upper receiver from palmettostatearmory.com ($319 great deal which may not last for those that are also in the market). The upper receiver I'm getting has the front-sight post on the barrel, which isn't a deal-killer but I would have preferred one like yours with the complete flat-top. I just couldn't find one for a good price though. I'm probably going to get a Magpul-BUS for the rear and probably a quad-rail to replace the stock hand-guard but other than that and some magazines that'll be it for my build.

I was pretty lucky and won a free three color Cerakote. I'm waiting until after the new year for a couple reasons to send it. 1. Making sure I'm armed in case shit hits the fan, 2. In case 12/21 doesn't mark the beginning of the zombie apocalypse and 3. shipping during the holiday season is iffy. I'm probably going to get it a woodland BDU style camouflage.

It's a Patriot Ordnance Factory P415. 16.5" barrel with a gas piston system. Base is about $1800 and comes with a pmag. I bought the MBUS sights, AFG and EOTech sight along with more pmags. Bought it from GunBroker.com.
